Testing a lab marker to predict oral cancer risk
This study looks at biopsy samples from mouth lesions that seem concerning, to see if a specific lab marker pattern can help predict whether oral cancer may be present or developing. It may help doctors sort which suspicious lesions need closer attention sooner.
Edmonton, AlbertaAges 15–90 - NCT04626440Recruiting
Testing DNA/RNA tools to study different breast cancer types
This study uses special DNA and RNA testing tools to better understand differences between breast cancer tumors in Taiwanese patients. It may help doctors choose more personalized treatment approaches by learning how tumors vary.
TaipeiAges 20 years+ - NCT04641702RecruitingPhase 4
Testing new esophagus study tools for achalasia patients
This study tests detailed ways to measure esophagus movement and symptoms in people with achalasia or other esophagus motility disorders. It may help doctors better diagnose these conditions and improve how treatment planning and outcomes are tracked.
Atlanta, GeorgiaAges 18 years+ - NCT04673981Recruiting
Follow-up study for oral and throat cancer pain
This study looks at nerve-related symptoms and pain in the mouth and throat in people who have been treated for oral or oropharynx cancer. You may be able to take part if you’re within 1 to 5 years after treatment and can follow study steps.
Clermont-FerrandAges 18 years+ - NCT04690972Recruiting
Collection of blood and tissue samples for liver disease research
This study builds a research library of biological samples (like tissue and blood) from people with chronic liver disease. It aims to create better lab and preclinical models of tumors and long-term liver problems, which may help future treatments.
StrasbourgAges 18 years+ - NCT04722913Recruiting
Link between forward head posture and neck headache
This study looks at whether a specific neck/head posture (forward head position) is related to cervicogenic headaches. It may help researchers understand what posture and neck factors contribute to these headaches.
GizaAges 18–25 - NCT04732273Recruiting
Study tracking long-term health after childhood cancer
This study follows people in Switzerland who finished treatment for childhood or teen cancer to learn about their long-term health. It may help doctors better understand late effects and follow-up needs after cancer treatment.
BaselAges Any age - NCT04732546Recruiting
Study of reproductive health in women with uterine variations
This study looks at how certain uterine (womb) variations affect diagnosis, treatment choices, and reproductive outcomes. It may help doctors better understand these conditions and improve care for affected women.
Ghent, East FlandersAges Up to 45 years - NCT04742608Recruiting
Liquid blood tests to diagnose thyroid nodules or cancer
This study tests whether a blood “liquid biopsy” can help diagnose thyroid cancer or hard-to-tell thyroid nodules without needing extra procedures. It may help confirm what’s going on before or around planned thyroid surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT04792684Recruiting
Collecting colon samples from adults with colon findings
This study collects body samples to help evaluate tests for people with suspected or newly diagnosed colorectal conditions, often around the time of colonoscopy or surgery. Depending on the arm, you may be asked to have a colonoscopy soon or to provide samples before planned surgery.
Chula Vista, CaliforniaAges 45–84 - NCT04804683Recruiting
FMD and SCAD registry study in Europe and beyond
This trial is a registry, meaning it collects detailed medical information to better understand fibromuscular dysplasia (FMD) and a specific type of heart-vessel dissection (SCAD) linked to FMD. It may help researchers learn who is at risk and guide better care in the future.
